FCS Fins K2.1 / V2
Performance Core or Glass Flex
(Grom | Thruster | Quad | 5-Fin)
FCS K2.1 Fins
*The FCS K2.1 Fins have now been discontinued and replaced with the FCS V2.
Kelly Slater designed the FCS K2.1 fins to be more maneuverable and faster off the top than the original FCS K-Fin.
The FCS K2.1 side and center fins have different templates, foils and flex patterns. With the K2.1's the larger, more upright side fins have greater flex for tighter and faster turns. The smaller, stiffer center fin adds control! The FCS K2.1's are Kelly Slater’s world winning template in Glass Flex, ideal for high performance in pocket surfing. You HAVE to add the FCS K2.1 Fins to your quiver if you don't have them yet!
The K2.1 Fins are the first of Kelly Slater’s world beating templates' now available in Performance Core. Kelly tested prototypes of the K2.1 fins in Performance Core through the 2nd half of ’08. The K2.1 Performance Core Fins have an upright template designed by Kelly with a smaller trailing fin. This is what Kelly rides in beach break and barrels and is ideal for tight turns and high performance in the pocket surfing.

FCS V2 Fins
FCS designed the FCS V2 fins to be more maneuverable and faster off the top.
The FCS V2 fins are designed for fast, critical surfing to get you in the pocket. This upright template produces quick start up acceleration. The FCS V2 side fins have a pivotal template that allows for tight turns in the pocket. These fins will give you speed and give you the maneuverability for fast, hollow, steep waves or that punchy beach break. This medium sized set is great for surfers from 140lbs to about 170lbs or the larger surfer that wants to loosen up their board. Ideally for performance boards with deep concave and moderate to extreme rocker, the FCS V2 fins will liven up any board. If you are looking for a fast, high performance fin the FCS V2 will deliver.

Other Thoughts: These fins are basically K2.1 tri fins plus G1000 for quad rears...The sides are slightly bigger than the original K2.1 and feel good. Abit more streamlined foil too...I liked the set as quads and they felt really smooth and drivey. Overall a good replacement for the K2.1 tri set with better Quad rears. These fins should probably be standard for every FCS user. Good fins.
